Watch out: The agent features are the newest and least reliable part. The free tier is a small monthly allowance, and Premium is still capped at 250 AI messages a month — only Ultra is uncapped, at nearly twice the price.

Watch out: Output needs more editing than the pricier tools, which is what you are trading for the price. The free tier is 10,000 characters a month, a few articles at most, and neither paid tier caps generation — the extra money buys tone matching across brands rather than volume.

Strong fit. Contact data, sequences and call recording in one place, so research and outreach do not live in separate tools.

Watch out: Contact data is never as accurate as the counter suggests, and the AI writes on top of whatever it found. Every plan is metered in credits, so what you pay tracks how much you export rather than how many people log in.

Watch out: Credits, not seats, so the bill tracks how much you run rather than how many people use it. The paid rates are starting points that the action and data-credit selectors push upward.

Two things separate these and both are on every card.
Fit
Whether a tool is built for this job, a strong fit for it, or
able to do it without that being its focus.
Free plan
Whether there is a tier you can keep using rather than a
trial that expires.
The order
Fit first, then a free plan, then alphabetical. There is
no score, no weighting we decline to publish, and nothing on this site a company can buy.
Questions
What is the best ai for cold email?
There is no single answer, which is why this page lists 8 rather than one: Copy.ai, ChatGPT, Claude, Writesonic, HyperWrite, Rytr, Apollo, Clay. 2 of them are built for this kind of work rather than able to do it. Start with a free one.
Which of these have a free plan?
7 of the 8: Copy.ai, ChatGPT, Claude, HyperWrite, Rytr, Apollo, Clay. Free means a real free tier you can keep using, not a trial that expires.
How was this list chosen?
By hand, from the 750 products this site tracks, and it is checked against the catalogue on every build — a product renamed or removed breaks the build rather than quietly disappearing from here. Nothing on this site can be paid for: no listing, no position, no wording.
